The Bureau is pursuing an active program to provide a temperature scale and thermometer calibration services in the range 1.5 to 20 Af.

Several germanium resistors have been thermally cycled from 300 to 4.2 Af and their resistances have been found to be reproducible within 1/3 millidegree when temperatures were derived from a vapor pressure thermometer whose tubing is jacketed through most of the liquid helium.

The average winter minimum for the entire state is 35 ° F ( 2 ° C ), and there is an average of 35 days in each year in which the thermometer falls below the freezing-point.

The question whether there is a limit to the degree of cold possible, and, if so, where the zero must be placed, was first addressed by the French physicist Guillaume Amontons in 1702, in connection with his improvements in the air thermometer.

In his Swedish paper " Observations of two persistent degrees on a thermometer " he reports on experiments to check that the freezing point is independent of latitude ( and of atmospheric pressure ).

A standard example is a Resistance thermometer.

Example: the actual temperature is 23. 234456544453 degrees but if only two digits ( 23 ) are assigned to this parameter in a particular digital representation ( e. g. digital thermometer or table in a printed report ) the quantizing error is: 0. 234456544453.

Daniel Gabriel Fahrenheit ( 24 May 1686 – 16 September 1736 ) was a Dutch-German-Polish physicist, engineer, and glass blower who is best known for inventing the alcohol thermometer ( 1709 ) and the mercury thermometer ( 1714 ), and for developing a temperature scale now named after him.

Temperature, as measured by an accurate, well calibrated thermometer, is empirical evidence.

Following the previous example, observer A might truthfully report that a room is warm, while observer B might truthfully report that the same room is cool, though both observe the same reading on the thermometer.

In his initial scale ( which is not the final Fahrenheit scale ), the zero point is determined by placing the thermometer in brine: he used a mixture of ice, water, and ammonium chloride, a salt, at a 1: 1: 1 ratio.

The temperature of the chamber is monitored either using a thermometer or thermocouple, and the temperature plotted against time to give a graph from which fundamental quantities can be calculated.

A thermometer ( from the Greek θερμός, thermos, meaning " hot " and μἐτρον, metron, " measure ") is a device that measures temperature or temperature gradient using a variety of different principles.

While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale.

The difference between a thermoscope and a thermometer is that the latter has a scale.

Though Galileo is often said to be the inventor of the thermometer, what he produced were thermoscopes.

The water level in the tube is controlled by the expansion and contraction of the air, so it is what we would now call an air thermometer.

The first registering thermometer was designed and built by James Six in 1782, and the design, known as Six's thermometer is still in wide use today.

This prospect did not please Mrs. King any more than did the possibility that her daughter might marry a Bohemian, but she used it to suggest to Thompson that, `` It is not in her nature to love you ''.

but this -- yes, terrible step I am about to take is lightened with an inundating joy by the new-found hope that here, in these poems, is treasure -- or at least some measure of beauty, which I did not know of ''.

There is every reason to recognize that in the very last years of his life, as we shall see, Thompson did take the drug in carefully rationed doses to ease the pains of his illness, but the exact date at which this began has never been determined.

Understanding, as he did, the difficulty of the art of poetry, and believing that the `` only technical criticism worth having in poetry is that of poets '', he felt obliged to insist upon his duty to be hard to please when it came to the review of a book of verse.

Master Gorton, having foully abused high and low at Aquidneck is now bewitching and bemaddening poor Providence, both with his unclean and foul censures of all the ministers of this country ( for which myself have in Christ's name withstood him ), and also denying all visible and external ordinances in depth of Familism: almost all suck in his poison, as at first they did at Aquidneck.

Nogaret is hardly an impartial witness, and even he did not make his charges against Boniface until the latter was dead, but there is some truth in what he said and more in what he did not say.

The favorite excuse of those who have now recanted their approval of communism is that they did not know how things would develop.

This is not to deny the existence of pogroms and ghettos, but only to assert that these horrors have had an effect on the nerves of people who did not experience them, that among the various side effects is the local hysteria of Jewish writers and intellectuals who cry out from confusion, which they call oppression and pain.

Brooks Robinson is great, and it is conceivable that he'll do even better in 1961 than he did in 1960.

The football opponent on homecoming is, of course, selected with the view that said opponent will have little more chance than did a Christian when thrown to one of the emperor's lions.

The drill press consists of a vertical shaft ( spindle ) which is tapered or threaded on one end to hold a drill chuck, a tubular housing ( quill ) in which the spindle is mounted, a head in which the quill is mounted, a feed lever which moves the quill up or down, a power source, and a movable table upon which the work is placed.

The size of the press is usually expressed in terms of chuck capacity ( the maximum diameter tool shank it will hold ) or distance between the spindle center and the column.

The only area in which American boys hold their own is the baseball throw.

Another factor that may hold hope is for parallel recognition is, as one man says it: `` that the fad for educating top people along managerial lines is yielding to the technically trained approach ''.

If the direct-sum decomposition ( A ) is valid, how can we get hold of the projections Af associated with the decomposition??
